Internal rendering engine makes all textures red, cycles renders have a pink tint
First screen shows that your file is using cycles nodes and is set to Blender Render. You cannot use them this way, you need to use the file with Cycles.

Second screen shows a lot of red because the sky texture is red, and that is casting onto all the objects.Cycles 'missing texture' is usually full magenta, not that dark red you see there. Try shifting to your World shader and check about changing to a white or even a sky texture to see what happens there.
